Hi Wi_fighter,
Good post idea. I'm a terrible pack rat . I have a Dennis the menace comic on the frig. where he's holding some nondescript piece of junk and saying I don't know what it's good for so I keeping it till I do. I doubt it is always OCD as I have had good reasons for not joining the throw away society perhaps like your own rooted in thrift.
I ran across a web based group on yahoo called Freecycle that might help there are many location based groups across the country, who list stuff they want and want to give away. So people may come to you to pick stuff up, and save landfill space. You have to give something before you can get, a nice idea.
Good luck with the messes~Down
ps ~ anyone want some 1978 popular science magazines, lol?
